Science / Biology / Myosin: Thick protein filaments in the center sections of sarcomeres.
Science / Biology / Sarcomeres: The functional units of skeletal muscle; consist of filaments of myosin and actin. MORE
Science / Biology / Sliding Filament Model: Model of muscular contraction in which the actin filaments in the sarcomere slide past the myosin filaments, shortening the sarcomere and therefore the muscle. MORE
